I have a friend who does not passcode protect her phone. I don’t passcode protect mine, either. I feel like anyone who needs a passcode on their phone is hiding something, and I simply don’t have time for it. So I don’t blame my friend for her lack of security.

In fact, I love it.

Whenever she leaves her phone behind, in a meeting, in her classroom, or even at the table for a minute or two, I grab it and begin to change her Facebook settings.

I change her relationship status from Engaged to It’s Complicated.

I change her birthday so she receives the barrage of birthday messages on the wrong day.

Your Facebook profile has a spot for your favorite quote. I once posted a quote about myself in her profile, and it took her more than a year to notice it.

It’s annoying as hell for her.

It’s funny as hell for me.

She’s not the only person I have done this to. I have hacked the Facebook profiles of two others, but they don’t know that I have done it yet. I have buried odd and embarrassing information in their Facebook profiles that they have yet to see.

It makes me so happy.

I mentioned this prank on Twitter over the weekend in a response to a comment about Facebook relationship statuses and received an enormous response from admiring and appreciative followers who never thought of pulling off a prank like this.

I was happy to help.

So go forth. Add a favorite quote to your friend’s Facebook profile. Change a religious affiliation. Assign a friend a February 29 birthday. Add a prison to the places where your friend once lived. Change a relationship status.

In the most recent case, changing my my friend’s relationship status from Engaged to It’s Complicated worked out well. When she reverted her status back to Engaged, it appeared in her friends’ feed again, and many, who failed to notice the change before, suddenly became aware of her pending nuptials. She received a barrage of congratulatory messages as a result.
